Gas turbine engine component with film cooling hole with accumulator

A gas turbine engine comprising:

• a compressor section;
• a turbine section;
• and
• a component arranged in one of the compressor and turbine sections, the component including:
• a wall providing an exterior surface and an interior flow path surface extending in a longitudinal direction;
• a film cooling hole extending through the wall and configured to fluidly connect the interior flow path surface to the exterior surface, the film cooling hole having a pocket facing the interior flow path and extending in the longitudinal direction, the film cooling hole having a portion downstream from the pocket and arranged at an angle relative to the longitudinal direction and extending to the exterior surface, the portion having an inlet at the pocket and extending to the exterior surface, wherein the pocket provides an opening in the interior flow path surface that is larger than the inlet, the pocket extends substantially in the longitudinal direction, extending in the longitudinal direction a greater amount than in a direction normal to the longitudinal direction, and the portion extends lateral at an angle in a range of 70°-179° relative to the longitudinal direction.
